Al-Cr_2O_3体系燃烧合成反应的热力学分析与实验

Thermodynamic Analysis and Experiment of Combustion Synthesis Reaction of Al Cr 2O 3 System

首先对ＡｌＣｒ２Ｏ３体系的燃烧合成反应进行了热力学分析，讨论了起始反应温度，Ａｌ２Ｏ３和Ｃｒ２Ｏ３稀释剂以及ＭｏＯ３添加剂对ＡｌＣｒ２Ｏ３体系的绝热反应温度的影响．最后对ＡｌＣｒ２Ｏ３体系进行了热爆和点燃模式的燃烧合成实验，并对实验结果进行了分析．

The thermodynamic analysis of combustion synthesis reaction of Al Cr 2O 3 system is conducted, and the influences of reaction starting temperature, diluents of Al 2O 3 and Cr 2O 3 as well as MoO 3 additive on the adiabatic combustion temperature T ad are discussed. At last, the combustion synthesis reaction experiments of Al Cr 2O 3 system under two different modes (self propagating mode and thermal explosion mode) are conducted and the experimental results are analyzed.
